fantasy and science fiction

My short list of scifict movie that is good science fiction are 

• disney pixar's up

This movie is a good science fiction because the main character in the story is Carl frederickson a 78 year old retiree does have a  floating house which is possible in real life it is proven with the nation geographic channel.here is the link that the floating house is proven by the national geographic channel http://goo.gl/Je0XX.

• Iron man

It is a good science fiction because this can be happen the main character wich is tony stark created powered suit of armor to save his life which is can be done into real life .

• the day after tomorrow 

Its is not far from the reality because it can t depicts the catastrophic effects of global warming in a series of extreme weather events that usher in global cooling which leads to a new ice age which is can be happen in time.

While this is my short list of weak science fiction

• Meet the Robinson

Basically the movie is an science fiction but have possibilities to be done in real world which is the time traveler spaceship that is not possible to have in future.

• G.I. Joe: The Rise of Cobra

this is a weak science fiction movie because it haven't been proven that the space ship and hi-technologies armors but it is possible to that it can be done or have in future.

• Cj7

Cj7 is a alien that had been sent in our world that Dicky found out on the junkyard and he named it cj7 is it is weak because it is not have been proven that the alien had been in our world. but there some studies that alien exist.

         difference between fantasy and science fiction

Based on my understanding about the difference of fantasy and science fiction

is that the fantasy is all about magical things that our mind think of. and 

it is basically like fairy tales stories that has a magical settings plot character

.this like a superhero's world where do we imagine that they have supernatural power

or powerful skills.its commonly like the movie that has a supernatural powers and 

magical stuffs.while the science fiction is commonly like fantasy but it does have 

more likely close to our world the real world.science fiction has some proof that some

certain things will be able come true.And science fiction has a lot of things that can 

be based on formulations, theories and inventions in the field of science.
